One major difference between Japanese and Western companies is that in Japan, no one person is usually identified as the personality or power behind a company’s policy or business strategy. Instead, ideas and strategies usually are...

There are only six basic types of machine. Discover more about planes, wedges and screws: what are they and why are they useful? Physics - Forces - Learning Points. Machines based on the ideas of Archimedes make work easier. An inclined...

This video explores five fun facts about polygons.

This problem is about the average power input to a wheel when we know the moment of inertia of the wheel, the change in angular velocity and the time interval.

This problem is about the average net torque on a wheel when we know the change in its angular speed, moment of inertia and change in time.

This problem is about the equation for the net torque on an cylinder with two radii in static equilibrium.

That’s right, we actually measure the rotational inertia of a bicycle wheel. How cool is that?

Review of the Rotational Dynamics topics covered in the AP Physics 1 curriculum.

1) Calculating if our answer makes sense. 2) Why can’t we sum the torques on everything? 3) Finding the force of tension.

In this episode of 2-Minute Linux Tips, learn the lsblk command. It provides information on block devices -- such as hard disks where you read and write one block of data at a time.

This video goes over a second application of the cross product and covers the basic concepts of torque which is also known as moment.

How to find the minimum coefficient for an object to roll without slipping on an incline.

A hollow sphere, solid sphere, and thin hoop are simultaneously released from rest at the top of an #incline. Which will reach the bottom first? Assume all objects are of uniform density. #RollingWithoutSlipping

A very basic introduction to the rotational form of Newton’s Second Law of Motion by way of its translational form.
